Sport: For Exercise

One Herr Doktor Siegfried Schiff, 66, a Berlin physician, said sternly
to reporters on the North Sea Isle of Heligoland, last week, that he
was about to take a swim "solely for exercise." Plunging in Herr Doktor
Schiff swam completely around Heligoland, about three miles, in 4 hours
and 35 minutes.
